Copper Tripeptide-1

What is it?

GHK-Cu (copper tripeptide-1) is a naturally occurring copper-binding peptide that declines in the body with age, used in skincare for its proposed role in supporting collagen production and wound healing.

What does it do?

Commonly used in anti-aging formulations. Reviewed evidence describes GHK-Cu's role in stimulating collagen and glycosaminoglycan synthesis, accelerating wound healing, and improving skin elasticity and density in cosmetic use, though much of the supporting evidence is preclinical/mechanistic rather than large-scale human clinical trials.
